"This time Provost takes his hidden camera to Las Vegas in 'Stardust' and uses the glorious and ambiguous power of the gambling capital to turn everyday life into an exciting crime story. In order to do this he even filmed real Hollywood stars such as Jon Voight, Dennis Hopper and Jack Nicholson."
Below is a short preview of Stardust (I can't find the full length version.)
The Haunch of Venison summary of the exhibition here.
